Ilanga kunye nomoya ziphindaphindeke kabini isabelo sazo sokuvelisa umbane wehlabathi ukusuka ku-2015 ukuya ku-2020. Umfanekiso: Amandla ahlakaniphile. Ilanga kunye nomoya zenze irekhodi le-9.8% yombane wehlabathi kwiinyanga ezintandathu zokuqala zika-2020, kodwa enye inzuzo iyafuneka ukuba iithagethi zeSivumelwano saseParis kufuneka kuhlangatyezwane nazo, itshilo ingxelo entsha.
Isizukulwana esivela kuyo yomibini imithombo yamandla avuselelekayo sinyuke nge-14% kwi-H1 2020 xa kuthelekiswa nexesha elifanayo lika-2019, ngelixa ukuveliswa kwamalahle kwehle nge-8.3%, ngokohlalutyo lwamazwe angama-48 olwenziwa yitanki yokucinga yemozulu i-Ember.
Ukususela ekubeni iSivumelwano saseParis sasayinwa ngo-2015, isola kunye nomoya ziye zaphindaphinda kabini isabelo sazo sokuvelisa umbane wehlabathi jikelele, ukunyuka ukusuka kwi-4.6% ukuya kwi-9.8%, ngelixa amazwe amaninzi amakhulu athumele amanqanaba afanayo enguqu kwimithombo yomibini evuselelekayo: i-China, i-Japan ne-Brazil. zonke zinyuke ukusuka kwi-4% ukuya kwi-10%;i-US inyuke ukusuka kwi-6% ukuya kwi-12%;kwaye iIndiya iphantse yanyuka ukusuka kwi-3.4% ukuya kwi-9.7%.
Iinzuzo ziza njengoko izinto ezihlaziyiweyo zithatha isabelo semakethi kwimveliso yamalahle.Ngokuka-Ember, ukuwa kokuveliswa kwamalahle kube ngenxa yokuhla kwemfuno yombane kwihlabathi jikelele nge-3% ngenxa ye-COVID-19, nangenxa yokunyuka komoya kunye nelanga.Nangona i-70% yokuwa kwamalahle ingabalelwa kukuhla kwemfuno yombane ngenxa yobhubhane, i-30% kungenxa yokwanda kokuveliswa komoya kunye nelanga.
Ngokwenene, iuhlalutyo olupapashwe kwinyanga edlulileyo yi-EnAppSyssifumene isizukulwana esivela kwiinqanawa zePV zesolar zaseYurophu zifike ixesha eliphezulu kwi-Q2 2020, siqhutywa ziimeko ezifanelekileyo zemozulu kunye nokuwohloka kwemfuno yamandla ehambelana ne-COVID-19.I-solar yaseYurophu eveliswe malunga ne-47.6TWh kwiinyanga ezintathu eziphelile nge-30 Juni, inceda ukuhlaziya ukuthatha i-45% yesabelo somxube wombane opheleleyo, olingana nesabelo esikhulu kunazo zonke ze-asethi.
Inkqubela enganelanga
Ngaphandle komzila okhawulezayo ukusuka kumalahle ukuya kumoya kunye nelanga kule minyaka mihlanu idlulileyo, inkqubela phambili akwanelanga ukukhawulela ubushushu behlabathi bunyuke ukuya kwi-1.5 degrees, ngokutsho kuka-Ember.UDave Jones, umhlalutyi ophezulu wombane e-Ember, uthe utshintsho lusebenza, kodwa alwenzeki ngokukhawuleza ngokwaneleyo.
"Amazwe ehlabathini lonke ngoku asendleleni efanayo - ukwakha ii-turbines zomoya kunye neepaneli zelanga ukuze zithathe indawo yombane ovela kumalahle kunye negesi yegesi," watsho."Kodwa ukugcina ithuba lokunciphisa utshintsho lwemozulu ukuya kwi-1.5 degrees, ukuveliswa kwamalahle kufuneka kwehle nge-13% minyaka le kule minyaka ilishumi."
Naxa sijongene nobhubhane wehlabathi jikelele, ukuveliswa kwamalahle kunciphise kuphela i-8% kwisiqingatha sokuqala sika-2020. I-IPCC's 1.5 degree scenarios ibonisa ukuba amalahle kufuneka ehle aye kwi-6% kuphela yesizukulwana sehlabathi ngo-2030, ukusuka kwi-33% kwi-H1 2020.
Ngelixa i-COVID-19 ikhokelele ekwehleni kwesizukulwana samalahle, ukuphazamiseka okubangelwe ngubhubhane kuthetha ukuba usasazo oluhlaziyiweyo lwalo nyaka luya kuma malunga ne-167GW, yehle nge-13% ekuhanjisweni kulo nyaka uphelileyo,ngokwe-International Energy Agency(IEA).
Ngo-Okthobha ka-2019, i-IEA yacebisa ukuba ukuya kuthi ga kwi-106.4GW yePV yelanga kufuneka isasazwe kwihlabathi liphela kulo nyaka.Nangona kunjalo, olo qikelelo lwehle lwaya kutsho kuma-90GW, kunye nokulibaziseka kulwakhiwo kunye nekhonkco lobonelelo, amanyathelo okuvalwa kunye neengxaki ezivelayo kwiiprojekthi zokuxhasa ngemali iiprojekthi ukusuka ekugqityweni kwalo nyaka.
